Bulk AlN + Al nanocomposite materials were Synthesized by sintering the compacts of AlN and Al nanoparticles, which were produced by an active plasma-metal reaction method. The sudeces of as-prepared nanocomposite was investigated by X-ray photoelectron spectroscopy (XPS).Results show the surfaces are much degraded and the degradation products are alumina(Al2O3),boehmite(AIOOH), bayerite(AI(OH)3) layer. The mechanism of degradation behaviour in moist environment was also discussed

材料科学技术（英文）

Ti-Fe nanoparticles with different concentrations were synthesized by gas condensation method.It is found that the size distribution of single phase nanoparticles obeys log normal distribution,and that of multiple phase nanoparticles is quite different. If it is assumed that the size distribution of each phase in multiple phase nanoparticles obeys log normal distribution as that of single phase particles. the calculated distribution curve is agreeable to the empirical curve. The inferences from the hypothesis are also supported by experimental results
